DETAILED DESCRIPTION

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below. Obviously, the drawings in the following description are merely some embodiments of the present invention. For those who skilled in the art, other drawings may also be obtained based on these drawings without paying any creative work.

As shown in FIGS. 1 and 2, the embodiment of the invention includes:

A super-silent intelligent water pump which is able to do self-priming by identifying of water flow whereas no necessity of water pre-filling includes pump body 1, diffusing plate 2, motor 3, impeller 4, vibration absorbing bracket 5 and a base 6, the motor 3 is disposed at the rear end of the diffusing plate 2, the impeller 4 is disposed between the diffusing plate 2 and the motor 3, the vibration absorbing bracket 5 is disposed between the pump body 1 and the base 6. In this embodiment, the pump body 1 is provided with a diffusing plate 2, the pump body 1 and the diffusing plate 2 are one-piece integrated structure which differs from the conventional pump body design, the conventional pump body designs diffusing plate separately from the pump body, and then takes time to assemble together, and the diffusing plate fixing is not good and easy to spin to lose performance, in this embodiment, the pump body is designed with a diffusing plate inside, and the diffusing plate and the pump body are designed as one piece, which simplifies assembly and stabilizes performance.

Among them, the pump body 1 is provided with a water inlet 11, a water outlet 12, a water filling plug 13 and a pulling ring 14, the water inlet 11 and the water outlet 12 are disposed on the left and right sides of the pump body 1 respectively, the water filling plug 13 and the pulling ring 14 are disposed at the top of the pump body 1.

The conventional self-priming pump must be filled with water in the pump body before pumping, and an injector must be installed in the pump body to meet the conditions of self-priming. In order to overcome these defects, the present invention solves this problem through the water guiding structure, as shown in FIG. 3, the diffusing plate 2 adopts a sealed single outlet structure, the diffusing plate 2 is provided with a diffusing plate water outlet 21, a diffusing plate water inlet 22 and a water guiding hole 23, the diffusing plate water outlet 21 is disposed on the outside of the diffusing plate 2, the water guiding hole 23 is disposed between the diffusing plate water inlet 22 and the diffusing plate water outlet 21. Among them, the diameter of the water guiding hole 23 is 1-50 mm. During the operation, negative pressure produced at the entrance as of the high speed rotation of the impeller 4, An open water cycle formed between the flow guiding hole 23 and the inlet of the impeller 4 since the diffusing plate 2 is a sealed single outlet structure, in such a situation, air flow is driven thereof. Along with the negative pressure at the inlet of the impeller 4 is getting larger and larger, the water is sucked into the water inlet 22 and the pump body 1, and then, the water is discharged out of the pump body 1 by high-speed centrifugation of the impeller 4.

The key factor for generating the self-priming function is the high speed rotation of the impeller. However, mechanical seals will heat up quickly due to long-term friction at high speeds, if there is no suitable heat dissipation measure, the rubber or plastic will be quickly melted by the high temperature, and causes the seal failure. In order to avoid this problem, this embodiment is shown in FIG. 4, a water drainage hole 41 with a diameter of 1-30 mm is designed at the inlet of the impeller 4, utilizing the principle of vacuum at the inlet of impeller 4, water will be sucked into the water drainage hole during operation, at the same time, under the effect of impeller 4 rotation, the cooling water will continue to circulate to the mechanical seal to dissipate heat.

As shown in FIG. 5, the vibration absorbing bracket 5 adopts an extended wings shape vibration absorbing bracket, and installation hole 51 is disposed on the vibration absorbing bracket 5. When the conventional water pump is working, due to the vibration of the motor itself and the water flow will generate a lot of noise, the screw of the water pump will loosen under the action of high amplitude, and the overall displacement will occur. After a period of time, the motor will fail, in order to solve this problem, the present invention utilize the characteristic of balance and ductility of the body of wild geese to solve this problem.

Further, the super-silent intelligent pump includes a noise reduction device 7, the noise reduction device 7 is disposed between the vibration absorbing bracket 5 and the pump body 1. There is a gap of 0-50 mm between the noise reduction device 7 and the motor 3. When the motor 3 is running, the vibration will be transmitted to the pump body 1 and the vibration absorbing bracket 5, at this time, the noise reduction device 7 will absorb vibration. And the vibration absorbing bracket 5 is extended in contact with the ground to increase the contact area, thereby further enhanced the effect of sound and vibration absorbing.

In this embodiment, the motor 3 adopts a brushless DC motor. Conventional pump motors adopts brush motors, which use their high speed to improve their self-priming performance, however, the lifetime of brush motors is only 200 hours and the noise will reach 60 decibels during operation, long-time using pump at a high-noise environments makes people irritable, in order to solve this problem, the invention combines a brushless DC motor with a water pump and has a service life of more than 2,000 hours, it works very quiet to achieve the purpose of a high-efficiency and super-silent, and the intelligent brushless motor has the effect of preventing blocking, preventing no load, preventing burning, and super-silent.

Among them, the motor 3 includes the motor front cover 31, the motor shell 32, the stator (not shown in Figure), the rotor (not shown in Figure), the motor rear cover 33, the controlling board 34 and the PCB housing 35, the motor front cover 31 is connected with the pump body 1 by screws, the stator and the rotor are disposed in the motor shell 32, the motor shell 32 is connected with the motor front cover 31 by screws, and the controlling board 34 is disposed in the motor rear cover 33, the heating components on the controlling board 34 are attached with the motor rear cover 33, the motor rear cover 33 is connected with the motor shell 32 by screws, and the PCB housing 35 is connected with the motor rear cover 33 by screws.

In the above, the motor front cover 31 and the motor rear cover 33 are made of cast iron or aluminum alloy or zinc alloy or copper alloy; the motor shell 32 is made of cast iron or aluminum alloy or zinc alloy.
